gclaims. e1. 12-33 This invention relates to certain improvements in presses of the typewhich'are employed in pressing an outer sole against the bottom of a shoe when the sole is attached-by a cementing process and more particularly to that type in which an angular shaped member simultaneously engages the heel and toe portions of the last,

to resist the pressure of the bladder when it is inflated to press the soleagainst the bottom of the shoe. i 7

Th objects of my invention are to provide a press which is suitable for a considerable range of sizes of shoes, so that by making a simple adjustment the press may be made effective for all shoes which are ordinarily manufactured, and with which uniform pressure on the sole throughout its entire length, may be secured. Also to provide a press with which the shoes may be placed in position and removed with increased facility without the manipulation of shoe clamping levers.

I accomplish these objects by means of the construction hereinafter described in the following specification and as illustrated in the accompanying drawings in which:

Fig. 1 is a side elevation of a press illustrating a preferred embodiment of my invention.

Fig. 2 is an end elevation thereof.

Fig. 3 is a detail view of the last engaging member.

Fig. 4. is a detail sectional view of the holding bar adjusting means.

Fig. 5 is a detail sectional view at line 5--5 of Fig. 4.

Fi 6 is a detail sectional view at line 66 of Fig. 1.

According to my invention an L-shaped frame is provided having a horizontally disposed base portion l and a vertically disposed arm portion l I. An inflatable bladder I2 is supported on the base portion to which an air supply l3 lead at its bottom, so that when the bladder is inflated it may be pressed against the bottom of a shoe held thereagainst, as in'all presses of this type.

I further provide a last engaging and holding member I4, which consists of a rigid casting of curved formation having an engaging portion I for the top side of the heel end of a last, and a forepart engaging portion It, so arranged that, when the portion I5 is engaged with the top of the heel end of the last, the portion [6 will bear on the top of the forepart of the last or of a shoe on the last. Said portion It has a pad I1 thereon, so that it will'not cause injury to the shoe upper.

The means for holding the member l4, against the action of the bladder when it is inflated consist of a bar 2ll'which isconnected at one-end to the upright arm portion ll of the frame by a pivot 2|. spaced hole 22 therein throughout the greater portion of its length. The top portion ofthe rocker arm It has a slot 23 in which thelower edge portion of bar 20 is located and the-ears formed by said slot have two holes 24, 2 i,'which are spaced with relation to 'the'holes 22, so that pins 26 may be placed in the holes 24, 25 and in two of the holes 22, to lock the member M to the bar, as shown in Figs. 1 and 6. A clip 21 is mounted astride the top edge portion of bar 20 and is connected thereto by a spline 28 and a screw 29 is threaded in the top overhanging portion ll of the arm H and has a ball 3E1 at its lower end which engages the clip 21 in a socket formed in the top side of the clip, the ball being attached to the clip by a clamp 3|, see Figs. 4 and 5.

As thus arranged the bar 20 and holding member M will be constantly supported, and the position thereof will not need to be changed for a succession of shoes of the same style and size. Adjustment for different sizes may be made by changing the position of the member M on the bar, and by adjusting the inclination of bar 20 by the screw 29, the clip 21 being slidable on the bar and the ball and socket connection permitting angular movement of the bar with relation to the screw.

When the bladder is inflated the member I4 is held in a position, suitable adjustments having been made, to hold the last and shoe thereon, so that a uniform pressure will be applied to the outer sole throughout its entire length. The construction may be such that the lower edge of the bar engages the bottom of the slot 23 in member l4 throughout the length of the slot, so that only one pin 26 is necessary to hold the member [4 rigidly with the bar, but if the bar does not engage the bottom of the slot in this manner a limited tilting of the member M with relation to the bar will be permitted if only one pin is employed, and it may be locked with relation to the bar if two pins are employed. With either arrangement the arm M will be held against tilting with relation to the bar when pressure is applied by the bladder.

The above described construction is such that Said bar has a series of'equally' adjustment may be made so that uniform pressure may be applied to all parts of the sole simultaneously and the shoes may be placed in position and removed with facility, as the member I4 is constantly supported, and it is merely necessary to inflate and deflate the bladder. Deflation of the bladder releases the shoe clamping pressure so that. theshoe can beremoved. from. the press without the' manipulationzofrvthe:member I4, bar 2F, or screw 29. Insertion of a second shoe and re-inflation of the bladder serves by itself to clamp the shoe in the press.
